CVE-2025-25510 affects the Tenda AC8 firmware version 16.03.34.06, exposing it to a buffer overflow vulnerability in the get_parentControl_list_Info function. This medium-severity vulnerability has a CVSS score of 6.5, indicating a significant risk to users if exploited. Vulnerabilities of this nature can lead to unauthorized access and manipulation of system components.
Risk to organizations includes potential unauthorized access to sensitive data and system controls. Attackers may leverage this vulnerability due to its relatively low complexity and no required user interaction. Therefore, organizations should prioritize patching immediately.
The vulnerability was published on February 21, 2025, and has been analyzed since then. Currently, there are no known exploits publicly available, which provides a window for organizations to implement necessary mitigations.
Given the potential impact and the nature of the vulnerability, immediate action is recommended to ensure systems are safeguarded against possible attacks.
Vulnerability Details
The Tenda AC8 firmware version 16.03.34.06 is vulnerable to a buffer overflow due to improper handling of data in the get_parentControl_list_Info function. The CVSS score of 6.5 indicates a medium severity, suggesting that while it poses a threat, exploitation is not trivial.
The attack vector is network-based, which means that an attacker does not need physical access to the device. The attack complexity is low, requiring no special privileges or user interaction.
The vulnerabilities are classified under CWE-120, indicating a buffer copy without checking the size of the input. This flaw could allow attackers to execute arbitrary code or cause a denial of service.
Technical Analysis
The root cause of CVE-2025-25510 lies in the inadequate validation of input size, leading to a buffer overflow condition. This vulnerability can be exploited through network interactions without requiring authentication or user participation.
The attack complexity is classified as low, which means that even less experienced attackers could potentially exploit it. There are no privileges required, indicating that any user can trigger the vulnerability.
Confidentiality and integrity impacts are assessed as low, reflecting that the vulnerability may not directly disclose sensitive information or alter data integrity. However, the lack of availability impact does not negate the serious nature of the exploit.
Risk & Impact Analysis
Real-world deployment of Tenda AC8 firmware may expose organizations to significant risks due to the buffer overflow vulnerability. The potential for exploitation could lead to unauthorized access or control over the device, allowing attackers to manipulate settings or intercept data.
The urgency for remediation is categorized as medium. Organizations should address this vulnerability in their priority patch cycle to minimize the risk of exploitation. The extensive use of Tenda devices in various networks heightens the blast radius potential if left unaddressed.
